IMPACT OF INDOOR AIR POLLUTION ON INFLAMMATORY BIOMARKERS AND CARDIAC AUTONOMIC CONTROL IN HEALTHY SUBJECTS AND PATIENTS WITH CONGESTIVE HEART FAILURE (APICE STUDY)
… organic compounds (VOCs) were monitored using a portable detector for 7 days. Together, a 7-day monitoring was performed through a wireless patch that continuously recorded electrocardiogram, respiratory activity and actigraphy. Indexes of CAC during sleep were derived from the biosignals: heart …
